Avenc de les Perles

The 2x1 metre entrance comfortably places us at the base of the first -17 metre pit, where we find a fissure. Following it eastwards, before reaching the end of the gallery, which ends in a narrow passage through which the outside can be seen, we will find a pit of about -15 metres that places us at the base of a fairly narrow fissure running SW-NE. Following it NE, it maintains a height of about 10 metres, ending a few metres further on; following it SW, the fissure descends on a slope of stones while winding in the same direction until reaching the -36 metre level, where it ends; the total length of the fissure is 42 metres. Returning to the base of the entrance pit, if we head SW, a steep 30º slope takes us to the only chamber in the cavity, formed from a widening of the fissure; the ramp continues with a steeper incline until reaching a new pit, which places us at -42 metres. We continue along the gallery for about 30 metres, until after a crawl the passage becomes completely impassable at -48 metres, this being the deepest point of the cavity.
